Forward Brenden Morrow has been placed on the injured reserve list with an upper-body injury, the Blues announced Monday evening. The veteran has been sidelined since Oct. 29.

Morrow, 34, joins forward Magnus Paajarvi on the injured reserve list, as he nurses, what the team is calling, an upper-body injury. The injury occurred in last Tuesday’s game when Morrow received a cross check to his ribs. The injury occurred late in the game, and forced Morrow to miss both Friday and Saturday’s games.

Morrow did not travel with the team for their four-game road trip, and was evaluated on Monday by Dr. Rick Wright. A diagnosis from Dr. Wright was given, and the Blues elected to place Morrow on IR based on that information.

Since the injury occurred on Oct. 29, it is expected to be retro-active to that date. If that is indeed the case, Morrow is eligible to come off IR as soon as Tuesday, but with the forward not currently skating and not traveling with the team, the earliest he would return would be on Saturday.

Morrow has played in nine games with the Blues this season and has posted three points (two goals, one assist). Two of Morrow’s points came in the Blues’ Oct. 10 win over Florida. After that, Morrow went six games without a point. His last tally, a goal, came in Tuesday’s victory over Winnipeg. This was also the game in which Morrow sustained his rib injury.

The veteran forward missed a game earlier in the season with a different upper-body injury. That injury was believed to be a neck injury.

Morrow was signed to a one-year contract late in the offseason and, though he wasn’t present for the full length of the Blues’ training camp, was given an every-day role by the team to start the season. He has played in nine of the Blues’ 12 games this season.

The Blues, expecting Morrow to miss the entirety of the road trip, called up Chris Porter from the American Hockey League’s Chicago Wolves last Thursday. Porter is traveling with the team, and played in Saturday’s loss to Tampa Bay.

The Blues currently have 13 forwards eligible to play. Paajarvi is believed to be inching closer to a return and because the Blues placed Morrow on IR, a Paajarvi return would put the Blues’ roster at the League’s limit of 23 players, meaning the team won’t have to make another roster move at that point.
